If a polyhedron has 5 faces and 5 vertices how many edges are there?

You can find this by using Euler's Formula which states: V + F = E + 2

V stands for the number of Vertices

F stands for the number of Faces

E stands for the number of Edges

Plugging in 5 for both F and V we get:

5+5=E+2

10=E+2

8=E

Which means there would be 8 edges.
